Application filed July 21, 1920.

T 0 all whom it may concern Be it known that l, ll/IATTS DAHLGREN,merchant, and a subject of the King of Sweden, residing atFalkijping-ltanten, in the Kingdom of Sweden, have invented cer tain newand useful Improvements in Win- (low-catches, and I do declare thefollowing to be a full, clear, and exact description of the invention,such as will enable others skilled in the art to which it appertains tomake and use the same.

The present invention relates to a window catch, to be placed betweenthe window post and the window, and is characterized essentially by thefact that the catch is on one of its broad sides provided with notchesby means of which it is adjusted in a recess in a fitting on the windowframe, which recess tapers conically downward and is open at the top.

A form of the invention is shown in the drawing, where Figure 3 showsthe fitting, fixed to the window frame, from the side, and Figs. 1 and 2the catch and the fitting from the side and from above respectively.

-1- designates the fitting, which is an gular and is fixed to the windowframe, its part which projects from the window :frame being providedwith a recess tapering conically downward and open at the top, in whichrecess the window catch -2 (Fig. 2-, 3) is inserted, the said catchbeing pro- Specification 01 Letters Patent.

Serial no. 397,856.

vided on one of its sides with notches which prevent the window catch-2- from sliding in the recess in the fitting -1-, but neverthelesspermit the window catch to be turned at different angles.

By the present invention is attained the advantage that the windows canbe locked gradually with a simple manipulation of the hand, without thewindows, as has hitherto been the case, shaking in windy weather, etc.,besides which the catch can assume any angle whatever in relation to thefitting. In the previously known devices this result cannot be attained,because there is always a certain amount of play between the hole in thecatch and the hook.

W hat I do claim as my invention and desire to secure by Letters Patentis:

, An element for attachment to a window frame and having a downwardlynarrowing recess in its upper side, and a catchjarranged to be placedbetween the window post and the window and provided on one of its broadsides with notches which enable said catch to be adjustably engaged insaid recess of said element.

In testimony whereof I have afi'ixed my si nature in presence of twowitnesses.
